NELSON HOLMES, OF YPSILANTI, MICHIGAN.

PUMP.

SPECIFICATION forming part of Letters Patent No. 234,189, dated November9, 1880.

Application filed March 6, 1880.

nl' To all whom tt may concern:

Be it known that I, NELSON HOLMES, of Ypsilanti, in the county of'Washtenaw and State of Michigan, have invented certain new and usefulImprovements in Pumps; and Ido hereby declare the following to he afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use it,reference being had to the accompanying drawings, which form part ofthis specification.

The object of my invention is to provide simple and eicient means forreadily connecting and disconnecting the pump-rod respectively with apump-handle and a windmill-pole.

The invention consists, first, in the combination, with a pump-handleprovided with a pivotal sleeve and a pump-rod` titted in the latter, ofa casing secured to the sleeve and a spring-pressed bolt which works insaid casing and engages or disengages the handle with the pump-rod,second, in the combination, with a pump-handle provided with alongitudinal slot and a horizontal roller fitted in the latter, ot' asleeve pivoted to the handle and tted over the pump-rod and a bolt whichconnects or disconnects said sleeve and pumprod; third, in thecombination, with a windmill-pole provided with a sleeve in which thepump-rod ts, ot a catch pivoted to the sleeve and a cam-lever adapted,by engagement with the upper arm of said catch, to throw the lower armofthe latter in or out of engagement with the notch ofthe pump-rod;fourth, in the combination, with a pump-rod provided with a notch and awindmill-pole having a sleeve in which the pump-rod ts, of a cam-leverpivoted to the sleeve and a catch pivoted to the sleeve, said catchhaving its lower extremity provided with a horizontal lug adapted toengage with the notch in the pump-rod, and its upper extremity beingprovided with a lug adapted to engage with the cam-lever when the latteris thrown up; fifth, in the combination, with a windmill-pole and apump-rod detachably connected thereto, of a pump-handle detachablyconnected to the pump-rod and provided with a slot and a fulcrum tted inthe latter, said fulcrum and slot being adapted to permit the handle tohave movement to and from the pump-rod independently (No model.)

of any movement of said fulcrum; sixth, in the combination, with awindmill-pole, a pumprod, and means for readily connecting ordisconnecting the two, ot' a pump-handle detachlably connected to thepump-rod and provided with an elongated slot and a roller-fulcrum fittedin the latter, said slot and roller-fulcrum being adapted to permit thehandle to have movement in the general line oi' its length independentlyof the roller-Fulcrum.

Referring' to the drawings, 1iligure l is a view, in rear and sideperspective, of so much ot' a windmill as is necessary to illustrate theinvention. Fig. 2 is a view in elevation-of the side not shown in thepreceding figure. Fig. 3 is a detail sectional view of the device forlocking the mill-pole and pump-rod together. Fig. 4 is a detailsectional view of the device for locking the pump-handle to thepump-rod.

The pump-handle A is made with a longitudinal slot, a, in which isiitted a horizontal roller, b, suitably mounted on the frame-work of'the mill. This construction permits the pump-handle to be operated inconnection with a straight vertical movement of the pum prod, inasmuchas the pump-handle has longitudinal movement on its roller-i'ulcrumcorresponding to the upward or downward stroke of the pump-rod. Asleeve, B, is pivoted to the handle and depends therefrom. This sleeveis titted over the pump-rod and is provided with a lateral casing, c. Ahorizontal bolt, O, works in said casing and is adapted to engage with ahole, d, formed in the pump-rod. A spiral spring, e, is titted over thisbolt. Its inner extremity engages the bolt, and its opposite extremityhas bearing against the outer end of the casing in which it Works.

By partially rotating the bolt a catch, f, formed on its handle engageswith the casing and maintains the bolt drawn out free from engagementwith the pump-rod. When the bolt is in engagement with the pump-rod thelatter is connected to the pump-handle.

In this manner the pump-handle may be readily connected or disconnectedwith the pump-rod, as desired.

In another application for United States Letters Patent on certainimprovements in windmills, led even date herewith, I show a pump- IOOrod detachably connected to a mill-pole by means similar to the abovefordetaehably connecting the puinp-handle to the pump-rod. Hence Irestrict this part of my invention to the specific combination of partsherein set forth.

The upper extremity of the pump-rod tits within a sleeve, l), secured tothe inill-pole. A catch, E, pivoted to said sleeve, has its upperextremity t'oriiied horizontally curved. A cam-lever, l", is alsopivoted to said sleeve, the cam portion of which is adapted to engagewith the curved arm ofthe catch and eause a horizontal lug. g, formed onthe lower arm of the catch to tit in a notch. h, formed in the pump-rod.

To disengage the pump-rod and mill-pole the cam-lever is thrown up so asto eause the lever to engage with a horizontal lug, l, formed 0n theupper extremity ofthe catch. The inclined position otthe eain-lever whenthe catch is free from the pump-rod causes the parts to be maintained inthis unloeked posi tion by the gravityot' the lever. ln this manner thepump-rod and mill-pole may be maintained in connected or disconnectedrelation, as desired.

The elongated slot in the puiiip-liandle. combined with theioller-t'ulcruni, permits` the han dle to have movement in the generalline ot its length to and from the punipa'od independently otanymovement otthe t'uleruni.

Having i'ully described my invention, what l claim as new, aml desire tosecure by Iietters Patent, is-

1. The combination, with a puniphandle provided with a pivotal sleeveanda pumprod tted in the latter, ot a casinar secured to the sleeve anda bolt whieh works in said easv ing and engagesoi'disengag'es the handlewith the pump-rod, substantially as set i'oi'th.

2. The combination, with a pump.||andle provided with a longitudinalslot and a horizontal roller titted in the latter, oi' a sleeve pivotedt0 the handle and titted over the pump-rod and a bolt which connectssaid sleeve and puinprod, substantially as set t'ortli.

3. The combination, With a mill-pole provided with a sleeve in which thepump-rod tits, of a catch pivoted to the sleeve and a cantileveradapted, by engagement with the upper arni of said catch, to throw thelower arm ot the latter in or out of engagement with the notch of thepump-rod, substantially as set forth.

4. The combination, with a pump-rod provided with a notch and amill-pole having a sleeve in which the plimp-rod fits, of a canileverpivoted to the sleeve and a catch pivoted to the sleeve. said catchhaving its lower extremity provided with a horizontal lug adapted toengage with the notch in the pumprod, and its lipper extremity beingprovided wtli a lug adapted to engage with the cam-lever when the latteris thrown up, substantially as set t'orth.

The eombination, with a windmill-pole and a pump-rod detachablyconnectedthereto, of a pmnp'handle detachably connected to the pump-rod andprovided with a slot and a ful crum titted in the latter, said fulcrninand slot being,r adapted to permit the handle to have movement to andfrom the pumprod independently ot" any movement of' said fulcrum,substantially as set forth.

(l. The combination, with a Windmill-pole, a pump-rod, and means forreadily connecting or disconnecting the two, of a pump-handle detachablyconnected to the pump-rod and provided with an elongated slot and arollerlulernm Iitted in the latter, said slot and roller-fulerum beingadapted to permit the handle to have movement in the general line of itslength independently ot' the i'ollcr-t'lilci'uni, substantially as setforth.

ln testimony' that I'claim theI foregoing,r I have hereunto set my handthis 24th day of February, ISSN.
